I'm not saying that you are solely at fault for the thread getting out of hand, but I hope we can agree that when things devolve to the point that we're talking about murdering other users and eating their corpses that the discussion has probably gotten out of hand.
I think there are ways of discussing even controversial topics without the conversation spinning out of control, but I know that this topic in particular touches a nerve with a lot of folks. Just please try to be mindful of whether you're escalating or deescalating the argument in the future.
